I think on Wednesday nights, you might only be able to buy plants and home decorations because souvenir shops usually open on weekends. If you want to go there, I recommend you go around 4 p.m.; after 8 p.m. the shops are, perhaps, closed due to Covid prevention measures.

Sorry, no idea.

Je ne sais pas répondre avec le COVID

Most shops inside the Chatuchak market close after sunset but there are plenty of market stalls, shops and food stalls in the surrounding area open during the evening.

Здравствуйте,если Вы имеете в виду магазины на Тепразите, то таких в Бангкоке я не нашла, покупала в Big C и в сетевых аптеках, есть еще отделы с тайской косметикой в больших ТЦ, но там цены выше, чем в ПТТ.

Hey, it is only weekend market actually, but there are many others you can find around bkk, you can find such a things at mbk mall.. it is street market at a mall...

No only Open for consumers and Public Saturday and Sunday. For business on Fridays.

Im sorry, I do not know the specific directions. Please however be prepared as Chatuchak is a huge outdoor market. Personaly, I found it very overwhelming

you can do it if you stay focused but i ended up seeing it at a leisurely pace and spent 6 hours there
